One of the springs 23 fits in a groove 28, Fig. 4, formed 1n the axle 15, thereby yieldingly retaining the same, so that by pulling 4upon the projecting end 29 of said axle, the

latter may be withdrawn. The brackets 16 have vertical slots 30 to permit upward play of the axle 15, as the paper ays off from the coil. The roll 21 is roviderI with an axle 31, upon the end of wiich bear springs 32, to cause the required pressure between' rolls 21 and 20.

A plate 33 extends down in rear of the feed roll 20 to deflect the strip downwardly, as it is fed out by the rolls.

Intermittent rotation of the roll 20 for the pu'rpose of advancing the strip line by line is effected by a pawl 34, engaging a ratchet wheel 35 secured to said roll, said pawl mounted upon a lever 36, and the latter pivoted at 37 upon one of the brackets 16. A returning sprin 38 for the pawl and lever holds the paw in enga ement with the ratchet wheel, and also ho ds a stop 39 upon the lever against the bracket arms 16. lThe preferred means for operating the lever comrises a fixed cam 40 placed in the ath of the ower end of the lever, s o that guring'the longitudinal or letter-feeding movement of the carriage, said lever. arm 41 engages the cam, and is thereby moved from the full line tothe dotted line position at Fig. 5, thereby actin through the pawl 34 to rotate the stripeeding ratchet-wheel 35. This movement takes place just before the strip reaches the rinting position, the cam being so related) to the point where the types 1 strike, at Fig. 1, that thestri is fed just before reaching the printing fie d. Hence whenever the carriage makes an excursion to and from the osition for Writing on said strip, the latter is ed in line space dlrection, although it is immaterial at what art of said excursion such feeding is done. t may be done upon the return stroke of the carriage. By this means the operator is relieved of all care as to the feeding of the strip, and needs only to write the entries thereon, the line-feeding bein cflcam whereveradjuste fected automatically for each entry, an no line feeding of the strip being effected during the insertion or writing of the bill, or at any time, except when an cntry is made upon the stri Trhe cam 40 is in the form of a plate adjustably secured by a collar 42, upon a fixed rod 43, whereby the cam may be adjusted in the direction of the travel of the carriage; a thumb screw 44 servin(r to hold the collar and The lever is held in the operative or dott-cd line position, at Fig. 5, by means of a straight edge or dwell portion/45; and upon the return of the carriage A45, and then down along the cam 40 to normal position. At the end of the straight edge 45 may-be formed a stop 46, which arrests the carriage, so that the lever may not ride off from the left hand end of the member 45. The rod 43 is mounted u on a pair of arms 47 detachably secured y screws 48 upon the framework. It will be seen that the strip feeding means may be detached from the machine, and the latter then be employed in the usual manner for writing upon wide paper along the entire length of the unipartite platen.

It will be seen that the stri feeding device is independent of the means or feedin bills or main sheets around the platen, the atter being operable independently of the strip feeding device; that the strip feeding device is operable to draw the strip around the platen while the latter is stationary; and that the two rolls 20 and 21 together with the core `15 hold the paper ribbon stationary.

In some instances, it is desired to make -a series of tallies of such a nature that` they must be made upon different strips, and in order to accomplish this result, I mount upon the carriage a second device for feeding the strip around the platen side by side with the strip which has been already described said device being substantially a duplicate of the one already explained, and designated generally as A, Figs. 1 and 3, the strip thereon being designated as B. Both of the line feeding levers may be opera-ted by the same cam 40, and ride along the same dwell member 45.

Between the strips u on the platen may run .that a provision of means for independently feeding a plurality of tally strips in combination with means for feeding a main sheet, is broadly' new, and it is not essential in all cases, that the precise means shown be employed for feeding the strips, nor that said plurality of strips be carried by a unipartite laten. The novel means for effecting the ine s acing, by movement of the carriage into t e field for w-riting the tally strip, may be employed in all "tally strip mechanisms.

In other instances, portions of my improvements may be used without others, and many variations may be resorted -to vwithin the scrpe of my invention.

aving thus described my invention, I claim:
